ABSTRACT:
Chain extended polyurethanes are prepared, using certain 3-(hydroxyhydrocarbylsecondaryamino)thiophene 1,1-dioxides, some of which are new chemicals. E.g., 3-(2-hydroxypropylamino)tetrahydrothiophene 1,1-dioxide is especially useful as a chain extender for high resiliency, flexible polyurethane foams.
